The Bureau of Reclamation has released for public review a draft Initial Study/Environmental Assessment for the proposed West Stanislaus Irrigation Districts Fish Screen Intake Project, to screen an existing 347 cubic feet per second unscreened diversion along the San Joaquin River.
In conjunction with project operations, the Bureau has installed a fish screen on a major diversion canal, built a fish ladder to restore upstream movement of endangered shortnose and Lost River suckers (Chasmistes brevirostris and Deltistes luxatus, respectively) into Klamath Lake, and removed a dam on an upstream tributary to facilitate sucker spawning.
One of the most costly projects is the $6 million Feather River fish screen, which is funded by Department of Fish and Wildlife, and Fish and Game grants and Yuba City's water fund.
There is insufficient evidence to reject the overall irrigation fish screen model for lack of fit (Hosmer and Lemeshow, p = 0.
In the last year alone, irrigators provided 60,000 acre-feet of water for endangered species, and the Klamath Irrigation District helped complete a state-of-the-art fish screen that will prevent the destruction of 1 million endangered suckers each year.
Further DNA analysis of such cells from a positive FISH screen could potentially confirm the identification of the female victim.
For downstream fish passage, EWEB would shut Carmen-Smith's secondary power plant at Trail Bridge, allowing fish to use its spillway rather than constructing a floating fish screen and a nearly mile-long transport pipe.
The Freeman Diversion on the Santa Clara already has a fish ladder - the only one operating in Southern or Central California - along with a fish screen that keeps smolts from ending up on farmers' fields.
The AECOM-led team will provide expert technical advice and consultation services, including: experimental design and implementation of non-physical fish barrier performance evaluations; fish screen monitoring and facilities design; field surveys for biological and physical parameters; study design and data analyses; regulatory permit acquisition; water resources planning; water quality modeling; and multi-dimensional model development and application.
But instead of a complicated "volitional" system that included an expensive fish screen and ladder as originally proposed, the parties have agreed to an alternative method of fish passage.
the project will involve replacement of the canal intake structure on creek and installation of a new fish screen and measuring device(s).
Remaining work includes construction of a fish screen and ladder; construction of a powerhouse tailrace connector; removal of a canal system; and removal of four diversion dams.
